Perlast

Precision Polymer Engineering Brand

Perfluoroelastomer (FFKM) is the most chemically resistant elastomer available and is effectively a rubber form of PTFE. Perlast® perfluoroelastomer grades provide other properties which prove most valuable in critical sealing applications where purity, high temperatures and retention of sealing force are paramount. The Perlast® range of perfluoroelastomer materials are at the leading edge of polymer technology. They have been developed to offer superior sealing solutions with enhanced performance and improved functionality, which is proven in the field (see case studies).

Perlast® G75B
  • Polymer Name:Perfluoroelastomer (FFKM)
  • Features:Heat Resistance, Acid Resistant, Good Thermal Stability, Low Water Absorption, Low Outgassing, Chemical Resistant, Low Compression Set, Steam Resistant
Description Perlast® G75B offers a unique blend of excellent chemical resistance, mechanical properties and high temperature stability, simultaneously extending the operating limits in all three aspects.Perlast® G75B has been specially formulated to provide increased acid resistance by eliminating fillers that are prone to acid attack and optimizing the polymer structure. In addition, this perfluoroelastomer has low permeability and as a result, it is less prone to swelling, leading to extended in-service performance in, for example, valves, pumps and mechanical seals.A high modulus makes Perlast® G75B resistant to extrusion and ideal for use in medium-high pressure applications. In addition, the low cumulative compression set provides a high mean-time between maintenance cycles in hot chemically aggressive environments.Perlast® G75B is suitable for both dynamic and static applications and can be fully molded into O-rings (any size up to 2m/6.5ft internal diameter) and custom shapes.Key Attributes Excellent chemical resistance to a wide range of chemicals Exceptional acid and amine resistance Superior mechanical properties Long-term sealing efficiency at high temperature Extremely low out-gassing properties Good steam resistance (ASME BPE 2000) Less than 2% swell in MIL-L-23699C jet oil after 336 hours at 200°C Typical Applications Aerospace Chemical Processing Diesel Semiconductor Oil & Gas
